Improving LZ77 Data Compression using Bit Recycling
Many data compression techniques allow for more than one way to encode the compressed form of data. In particular, this is the case for the LZ77 technique and its derivatives, where matches can often be described in more than one way. The very existence of multiple encodings for the same data acts as a side-channel through which additional information can be conveyed from the compressor to the ...
متن کاملParallel Hardware/Software Architecture for the BWT and LZ77 Lossless Data Compression Algorithms
Nowadays, the use of digital communication systems has increased in such a way that network bandwidth is affected. This problem can be solved by implementing data compression algorithms in communication devices to reduce the amount of data to be transmitted. However, the design of large hardware data compression models implies to consider an efficient use of the silicon area. This work proposes...
متن کاملRecycling Bits in LZ77-Based Compression
We present a technique that exploits the multiplicity of the ways a text may be encoded using an LZ77-based compression method. With such methods, repeated parts of the text are encoded as length-distance pairs that refer to previously seen text. In general, given the maximum length of a repeated part, there may be more than one distance at which there is a copy of the repeated part. The compre...
